Description Twenty diverse pearl millet genotypes ranging from landraces to high yielding hybrids were studied for genotypic variation in nitrogen (N) use efficiency in high (100 kg N/ha) and low fertility (20 kg N/ha) over two years in the field.

The combined data over years and fertility levels indicated that despite taking up similar amounts of N, genotypes differed significantly in biomass production and thus in N use efficiency. A West African genotype, Souna B, had N use efficiency values 32% higher than the less efficient Indian genotype BJ 104 even though both genotypes had similar N uptake. An increase in N fertility decreased N use efficiency since the percentage increase in biomass was smaller than the percentage increase in N uptake.
